当前，关于带式输送机承载段支撑托辊间距对压陷滚动阻力影响的研究相对较少，而该方面的深入探究可为带式输送机节能降耗提供关键的理论依据，为研究托辊间距与环境温度对带式输送机压陷滚动阻力的影响规律，综合运用了理论分析、有限元建模、仿真分析与实验验证的方法，以织物芯输送带为研究对象，在Abaqus软件中构建输送带和托辊模型，模拟托辊间距在800 ~ 1 200 mm、环境温度介于-10~30 ℃多种工况下进行仿真分析，得出仿真结果。最后为验证环境温度对压陷滚动阻力影响的仿真结果，进行了实验研究。经分析，获得如下主要结论：在环境温度为-10~30 ℃工况下，托辊间距从800 mm递增至1 200 mm时，压陷滚动阻力值增幅均超过1.3%，在20 ℃工况下增幅超过5%，且应力值与阻力值均随温度升高而降低，不同托辊间距工况下，温度上升时二者下降趋势保持一致；实验研究结果表明在多种载荷下，压陷滚动阻力随温度增高呈下降趋势，将实验结果与仿真结果对比，发现曲线趋势基本相同，验证了仿真结果的正确性。

Currently, there is limited research on the effect of support roller spacing on the indentation rolling resistance in the carrying section of conveyor belts. In-depth exploration in the area can provide crucial theoretical support for energy-saving and consumption reduction in conveyor systems. To investigate the influence of roller spacing and environmental temperature on the indentation rolling resistance of conveyor belts, a comprehensive approach combining theoretical analysis, finite element modeling, simulation analysis, and experimental validation was applied. A fabric core conveyor belt was selected as the research object, and models of the conveyor belt and rollers were constructed in Abaqus software. Simulations were conducted under various conditions, with roller spacing ranging from 800 mm to 1 200 mm and environmental temperatures between -10 ℃ and 30 ℃. The simulation results were obtained. To validate the effect of environmental temperature on indentation rolling resistance, experimental studies were carried out. The analysis revealed the following key conclusions: under conditions with environmental temperatures ranging from -10 ℃ to 30 ℃, when the roller spacing increased from 800 mm to 1 200 mm, the increase in indentation rolling resistance exceeded 1.3%, with an increase of over 5% at 20 ℃. Both the stress and resistance values decreased as the temperature rose, and the trend was consistent across different roller spacing conditions. Additionally, experimental results indicated that under various load conditions, the indentation rolling resistance decreased as the temperature increased. A comparison between the experimental and simulation results show a similar trend, confirming the accuracy of the simulation outcomes.
